CLOCK.

' I Application filed. May 26, 1924. Serial No. 715,891.

To' all whom it may concern: I

Be it known that I, HERMAN MAIBAUER,

citizen of the United States,- residing at Detroit, in the county ofWVayne and State I of- Michigan, have invented a new anduseful to" timeso thatthe sleeper will not become accustomed to the particular sound ofthe alarm is an object of the present invention;

Another object of the present invention is to provide an alarm' clockhaving a plurality of alarm sounding members which may be operated inconjunction with each other' or which may be operated singly, the toneor sound of the different alarm members being different so as to producedifferent effect upolr thesense of hearing.

Another object of the invention is the provision in an alarm clock of aplurality of alarm members adapted for operation by astriking member,and so' mounted as to be adjustable relatively to the striking member soas to produce in the various positions of adjustment a different soundor tone depending upon the point of contact of the striking member withthe alarm member.

Another object of the invention is the provision of an alarm clockhaving a plurality of alarm members and means for carrying the same, thestructure of which will be simple, economical and durable;

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed. j

The invention will be" best understood from a reference to theaccompanying drawings which form a part of this specification and inwhich,

Fig. 1 is a front elevational view of the invention,

Fig. 2 is a side elevational view of the invention,

Fig. '3 is a bottom plan view of the in vention,

4 is an enlarged fragmentary side elevational view of one of thesupporting legs,

F 5 is a fragn'ientary front elevational view of a modified form of theinvention,

F 6 is a fragn'ientary top plan viewof the supporting bar and soundingmember shown in 5;

The invention, in its preferred form, comprises an alarm clock 9 of theconventional structure having an alarm operating stem 10 projectingtherefrom and provided with a striking head 11. Mounted on oppositesides of the casing of the clock 9 are a pair" of arcuate legs '12 and12, suitablerivets being projected through the ends of the legs andthrough the casing of the clock for securing the ends in operativerelation thereto.

As shown in Fig. 1, the ends of the legs 12 and 12 are cut arcuately asat 13 and 13' respectively, so as to lie in contact with the peripheryof the clock, the extreme ends of the legs at this arcuate out beingvery thin so as to taper oil gradually to the periphery of the clockcasing. The free ends of the legs 12 and 12 are provided withtongues'14, 15 and 16, which are folded upon the main body of the legsso as to embrace a strip 17 Y of rubber having a pair of tongues 18 and19 which project outwardly from the ends of the legs intermediatethetongues 14, 1'5 and 16, so as to form a soft, yielding, contactingsurface with which the legs engage against the supporting member uponwhich it is placed. An alarm supporting bar 20 connects the legsadjacent their free ends, the connection of the ends of the supportingbar 20 with the ends being made in any desirable manner; such as,riveting or proectm'g integral tongues from the supporting memberthrough slots formed in the legs. The supporting member is provided witha pair of elongated slots 21 and 22. It will be noted in Fig. '1, thatthese slots are not positioned the same distance from the striker ii.The slot 22 is positioned a greater distance from the striker 11 than isthe slot 21. Projected through the slot 22 is a bell stem 2. upon whichis fixedly mounted a collar 2 L, the free end of the bell stem 23 beingthreaded to accommodate a wing nut 24, the opposite end of said stembeing fixedly mounted in a bell or alarm member 25.

Projected through the slot 21 is a bell. stem 26 having a collar 26fixedly mounted thereon and threaded at its free end to accommodate. awing nut 2st, the opposite end of said bell stem being fixedly mountedon a bell or alarm sounding member 27. It will be noted that the bell 25is of larger dimensions than the bell 27. By forming these out of thesame material and arranging them in different sizes, as shown in thedrawing, it is apparent to those skilled in the art, that a striking ofthe bells will give off a different tone. In operation when the strikingarm is brought into contact with the bells, an alternate sounding ofeach will be had commingled with the alternate sounding of the other, toproduce a discordant or harmonious sound depending upon whether thebells are in harmony or not. By adjust ing the bells relatively to thestriker and permitting the striker to strike the bell near the lip ornear the base will cause the bell to give off a different tone, or atleast give off notes of different intensity. In this way the bells maybe so adjusted as to vary the sound which is given off upon a ringing ofthe alarm so that the sleeper may be roused by a new combination ofsounds.

By removing one of the bells entirely, the clock may be used as an alarmclock ringing only one of the bells. After the sleeper has becomeaccustomed by repeated ringing of the bells on different days to thesound set forth by the same bell, the bell may be changed and a new onesubstituted therefor. The new bell may be of different material or ofdifferent size, as desired, the different materials giving off differentnotes when formed into bells of the same size. In the construction ofthe device the applicant prefers to employ brass bells as the tone givenoff is a clear and distinct one. However, the material of which thebells may be made is optional with the one constructing the same. Ifdesired, chimes may be used instead of a separate pair of bells, thechimes brought into play as desired by adjusting the mounting of thesame upon the supportmg member 20. i

By arranging the slots 'in the bars at varying distances from thestriker, the mount of the bells of various sizes is permitted.

In Figs. 5 and 6, I have shown a striker 28 mounted on the clock 9adapted for reciprocal movement so as to strike a Xylophone bar or othersounding bar 29 mounted on the supporting member 20, the supportingmember 20 in this case being channel shaped and provided with sideflanges 30 and 30 to prevent the bar :29 from removal therefrom, asuitable layer of felt or the like being interposed between the bar andthe upper surface of the supporting member 20 to sepa rate the metallicmembers, it being desirable that the legs 12 and 12' and the supportingmembers 20 and 20 be made from metal. However, this is also optionalwith the one constructing the device, as other suitable material may bediscovered which would serve the purpose equally well. The striker 2Sreciprocating will be brought into contact with the bar 29 so as toproduce the sound to effect the alarm. It is apparent that the bar 29may be of any desired length and may be removed at will and replaced byanother of different length, so as to give off a different tone ofsound.

hile I have illustrated and described the preferred form of structure, Ido not wish to limit myself to the precise form of structure shown, butdesire to avail myself of such variations and modifications as comewithin the scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is: r
